Solar Energy Potential in Bonito, Brazil
Bonito, Brazil, located in the tropical region at latitude -8.5224, longitude -35.6945, offers promising conditions for solar energy generation throughout the year. The tropical location provides relatively consistent sunlight patterns, with seasons characterized more by wet and dry periods rather than dramatic temperature changes. The solar energy production potential varies across seasons but remains substantial year-round. In Spring, panels can generate an impressive 6.73 kWh per day for each kilowatt of installed capacity, making it the most productive season. Summer follows closely with 6.27 kWh/day, while Autumn yields 5.36 kWh/day. Winter, though the least productive season, still provides a respectable 4.72 kWh/day.Optimal Panel Installation
For fixed solar panel installations in Bonito, the ideal tilt angle is 7 degrees facing North. This specific angle has been calculated to maximize year-round energy production based on the location's position relative to the sun's path throughout the year. This relatively shallow tilt reflects Bonito's proximity to the equator, where the sun passes nearly overhead during much of the year.Environmental and Weather Considerations
Several factors could potentially impact solar production in this tropical location:- Heavy rainfall during the wet season can reduce solar efficiency due to cloud cover and direct precipitation on panels
- High humidity levels may cause condensation on panels, potentially reducing light transmission
- Dust accumulation, particularly during dry periods, can gradually decrease panel efficiency
- Potential for tropical storms that could physically damage installations
Preventative Measures
To maximize solar energy production in Bonito despite these challenges, several preventative measures are recommended: Installing self-cleaning panel systems or implementing regular maintenance schedules can address dust and debris buildup. Weather-resistant mounting systems designed to withstand tropical storms should be prioritized. Additionally, slightly increasing the tilt angle beyond the optimal 7 degrees can improve natural cleaning from rainfall, though this comes with a minor reduction in theoretical maximum output. Incorporating micro-inverters or power optimizers can help minimize production losses when parts of the array are shaded or affected by weather conditions. Finally, proper drainage systems around ground-mounted installations will prevent flooding issues during heavy tropical downpours. With these considerations addressed, Bonito's consistent year-round solar potential makes it an excellent location for solar PV installations, with particular productivity peaks during the spring and summer months.Note: The Tropics are located between 23.5° North and -23.5° South of the equator.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 3161 locations across Brazil. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Bonito, Pernambuco
Seasonal solar PV output for Latitude: -8.5224, Longitude: -35.6945 (Bonito, Pernambuco, Brazil), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:
 
Ideally tilt fixed solar panels 7° North in Bonito, Pernambuco, Brazil
To maximize your solar PV system's energy output in Bonito, Pernambuco, Brazil (Lat/Long -8.5224, -35.6945) throughout the year, you should tilt your panels at an angle of 7° North for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.
Seasonally adjusted solar panel tilt angles for Bonito, Pernambuco, Brazil
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Bonito, Pernambuco, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 7° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 7° South in Summer | 14° North in Autumn | 24° North in Winter | 2° North in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Bonito, Pernambuco, Brazil
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Bonito, Pernambuco, Brazil.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Bonito, Pernambuco, Brazil
The topography around Bonito, Brazil presents a diverse landscape characterized by undulating hills, valleys, and plateaus typical of northeastern Brazil's coastal region. Positioned in Pernambuco state, this area features a transition zone between the more elevated inland regions and the coastal lowlands. The terrain generally slopes from west to east, with elevation gradually decreasing as one moves toward the Atlantic Ocean. Bonito sits within what is known as the Borborema Plateau region, with numerous hills and small mountains punctuating the landscape. The elevation in this area typically ranges between 400-800 meters above sea level, creating a moderately rugged profile. This hilly terrain is interspersed with flatter areas and valleys carved by seasonal streams and rivers that form part of the local watershed.
Soil and Vegetation Characteristics
The region features a mix of soil types, predominantly latosols and podzolic soils, which have developed under the influence of the local climate. These soils support a transitional vegetation pattern between the Atlantic Forest (Mata Atlântica) and the drier Caatinga biome. While much of the original forest cover has been modified by human activities, patches of native vegetation remain, particularly in steeper areas less suitable for agriculture.Solar PV Suitability in Surrounding Areas
For large-scale solar photovoltaic installations, the most suitable areas near Bonito would be the flatter plateaus and gentler slopes that offer several advantageous characteristics. The northwestern and western regions of Bonito present promising opportunities due to their relatively level terrain and reduced forest cover. These areas typically have slopes under 5 degrees, making construction and maintenance of solar arrays more feasible and cost-effective. The northeastern corridor extending toward Recife also contains several suitable zones where the topography flattens considerably. These areas benefit from stable ground conditions and minimal flood risk, important considerations for infrastructure investments of this nature.Topographical Challenges
Some regions around Bonito present challenges for solar development. The more steeply sloped hillsides, particularly those with gradients exceeding 10 degrees, would require significant grading work that increases both environmental impact and project costs. Areas with dense remaining forest cover also present ecological concerns and would likely face more stringent environmental licensing requirements. The southeastern quadrant contains more complex terrain with a higher density of streams and seasonal water bodies. These hydrological features create potential complications for large-scale installations and might necessitate more sophisticated drainage systems.Accessibility Considerations
The existing road network around Bonito provides reasonable access to many of the topographically suitable areas, particularly along the BR-104 corridor. This infrastructure advantage reduces the need for extensive new access road construction, which can be a significant cost factor for remote solar installations. In conclusion, the most promising areas for large-scale solar PV development near Bonito would be the flatter plateaus to the northwest and northeast, where the combination of suitable topography, reduced vegetation constraints, and existing infrastructure creates favorable conditions for solar energy development.Brazil solar PV Stats as a country
